Perl Data::Dumper

#!/usr/bin/perl
use Data::Dumper qw(Dumper); 
my %hash = ( a => 1, b => 2, c => 3 );
print Dumper(\\%hash);  # note the \ backslash; Dumper() takes referenc
+es as arguments

$./example
Output: 
$VAR1 = {
          'c' => 3,
          'a' => 1,
          'b' => 2
        };

lets do one more modification

#!/usr/bin/perl
use Data::Dumper qw(Dumper); 
my %hash = ( a => 1, b => 2, c => 3 );
print Dumper(\\%hash);  # note the \ backslash; Dumper() takes referenc
+es as arguments

$./example
Output: 
$VAR1 = {
          'c' => [
                   0,
                   1,
                   2,
                   3
                 ],
          'a' => 1,
          'b' => 2
        };
